Mueller Streamline ELL00886 Copper 90 Deg Elbow 1/4 in

Product Description

The MUELLER STREAMLINE ELL00886 is a wrot copper 90-degree long radius street elbow designed for sweat-connection copper tubing systems. Built in a FTG x C (fitting-to-copper) configuration, it accepts a 1/4-inch fitting on one end and a 1/4-inch copper tube on the other. The long radius geometry reduces flow restriction compared to standard short-radius elbows, making it a practical choice where low pressure drop matters. At 0.02 pounds, this compact fitting measures approximately 1.31 inches in height and 1.4 inches in depth. It is a go-to component for licensed plumbers and HVAC technicians routing small-diameter copper lines in tight spaces.

This elbow is suited for residential and light commercial applications involving 1/4-inch copper tubing runs, including refrigeration tubing, condensate lines, and low-pressure plumbing branch connections. The street configuration — with one male fitting end — allows direct insertion into another fitting without an extra coupling, saving space in confined installations. Typical install scenarios include coil piping connections, refrigerant line routing, and fixture supply work where a 90-degree change of direction is required.

Key Features

• Wrot copper construction for reliable, leak-resistant brazed or soldered joints
• Long radius bend reduces turbulence and pressure drop through the fitting
• Street (FTG x C) ends allow direct fitting-to-fitting connection without an additional coupling
• 90-degree angle suits standard direction changes in copper tubing runs
• Compact profile — 1.31 inches height, 1.4 inches depth, 0.44 inches width — fits tight mechanical spaces
• Lightweight at 0.02 pounds, minimizing load on small-diameter piping assemblies

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/4-inch copper tubing systems using standard FTG x C sweat connections.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician following applicable local plumbing codes and ASTM B75 or B88 copper tubing standards. Shut off and depressurize the system and drain any standing fluid before cutting or removing existing fittings. Clean tubing ends and fitting sockets with emery cloth and apply flux evenly before soldering or brazing. Avoid overheating the fitting during the joining process, as excessive heat can damage adjacent components or compromise the joint.
